CHARLES G. ANTHONI, OF PARIS, FRANCE.

PHOTOGRAPHIC APPARATU S.

specification forming part of Letters Patent No. 33,230, dated September10, 1861.

T0 all whom it may concern:

Be it known that I, CHARLES GUs'rAvE ANTHONI, mechanician, of Paris, inthe Empire of France,have invented Improvements inPhotographicApparatus; and I do hereby declare that the following is a full, clear,and exact description of the same, reference being had to the annexedsheet of drawings, making a part of the same.

This invention consists in a certain mode of applying the sensitizingand developing baths, in combination with the camera, and in certainmechanism capable of being con- I trolled outside of the apparatus,whereby I obtain a complete photographic apparat-us for Operating upondamp collodion in the open air or in any other place,in which I cansensitize the plate, take the picture, and transfer the plate to thedeveloping-bath without removing the picture from the dark room formedby the camera and baths.

Figure l in the drawings is a side view of the exterior of the apparatuspacked up for traveling. Fig. 2 is a central Vertical section of thesame, having the box E shown in Fig. 1 removed and ready for use. Fig. 3is a plan corresponding with Fig. 2. Fig. 4 represents a portion of themechanism for holding the plate during the processes of sensitizing itand taking the picture. w

Similar letters of reference indicate corresponding parts in the severalfigures.

A B O D is the camera-box, of which the Vertical portion A andhorizontal portion B are permanently secured together. The portion O, towhich the tube containing the object-glass is to be attached at a,Fig.2, is connected by a square bellows-like tube b, and the portion D' ishinged at c, Fig. 3, to swing open with a horizont-al moveinent, asillusl trated by red lines in Fig. 3, and at d to swing open by adownward movement, as illustrated by red lines in Fig. 2.

e e are hooks to fasten the portion O when -closed up, and when theportion O is closed up there is room left above the portion B for thebox E, in which is to be carried a number of sheets of glass and avessel containing water in which to iminerse the plates when they arei'einoved from the deyeloping-bath. Before this box E can be packed uponthe camera the tube containing the object-glass is to be turned roundwithin the camera-box.

The portion D of the camera-box contains the gutta'perchasensitizing-bath F, (see Fig. 2,) such bath being a fixture within it,and the portion B contains the gutta-percha de- Veloping-bath G, whichis movable at a door h in front.

H is a sliding screen titted to the part D of the camera-box forintercepting theluininous rays while the sensitizing process isperformed, fitted with a yellow glass through which the process ofsensitization may be observed. This is withdrawn previous to taking thepicture by taking hold of a strap j at the top thereof.

7a k., Figs. 2 and are hooks of gutta-percha, horn, whalebone, or othersuitable material secured to the front of the portion D of thecamera-box for the support of the lower edge of the plate Z, on whichthe picture is to be taken, and k' k', Fig. 2, are hooks secured to ashaft m, passing through bearings in the upper part of D to hold theupper edge of the plate. The hooks 71" k' are caused to press upon theupper edge of the plate by a coiled spring m', applied to one end of theshaft m, outside of the camera-box.

k k, Figs. 2 and 4:, are hooks attached to a shaft n, passing throughbearings in the lower part of D for the purpose of removing the platefrom the hooks 7a 7a and transferring it to the developing-bath G, aswill be presently explained. These hooks k lt are kept below the hooks kk until the time for transferring the plate by means of a coiled springn', applied to one end of the shaft n outside of the camera-box. Theshaft n is furnished outside of the camera-box with a knobn, by which itcan be turned by hand in the direction of the arrow shown near it inFig. 1, which is the opposite direction to that in which its springtends to turn it. The shaftn' has provided for it movable i bearings rfr, by which it may be adjusted higher or lower to adapt the hooks toplates of different sizes.

p is one of two lateral guides to guide the plate on its way from thehooks k k' 7a' to the developiug-bath G.

q q are hooks-two upper and two lower ones-working on pivots 5 5 withinthe portion A of the camera-box and capable of having their notches 6 6brought to such positions relatively to A as the hooks k and k' k'Occupy when the portion D of the camerafl box is shut up, as shown inbold outline in Fig. 2, the object of such hooks being to hold theground glass by which the focus of the camera is adj usted.

The sensitizing-bath F is so constructed that when the part D of thecamera-box is let down to a horizontal position it (the said bath)constitutes a fiat-bottomed trough, but that when it is upright, asshown in bold Outline in Fig. 2, a reservoir 8 is formed in its lowerpart to contain the sensitizing solution. This reservoir may be fittedwith a lid at s', Fig. 2, to prevent the solution splashing about whilethe apparatus is carried from place to place.

The developing-bath G is made with an inclined plane t, down which theplate may slide into it from the hooks k 7a k lc, and the said bath isfitted with a movable strip u, by which the plate can be removed. Themouth 'a' of the said bath may be fitted with a lid to prevent thede\-'eloping solution from splashing about. To enable thedeveloping-bath to be inclined in opposite directions that the solutionmay run all over the face of the plate, the portion B of the camera-boxis connected by hinges w and x with two boards I and J, which permit thebox to have a rocking motion, while the lowerboard J is attached to atripod by the screw K, and also permits the adj ustment to elevate ordepress the focus. The elevation is, secured by a slotted plate L andset-screw L' (Shown in Figs. 1 and 8.)

y is a hook secured to theportion D of the camera-box to receive a metalstrap z, attached to the part A for the purpose of holding the portion Din a horizontal or nearly horizontal position while the focus of thecamera is being adjusted.

6-7 8 are small pendulums attached to the different portions of thecamera-box to facili-` tate the adjustment of the several ,portions 9isa hook to secure the Vportion 'D of the camera when it is not desiredto open at the hinge c.

10 is a hook to secure the portion D when closed up to the portion A.

I will now proceed to descri'bethe mann'er in which the apparatus isused. After setting the apparatus up on its stand I adj ust it by thependulum 6 to bring'the hinge d to a horizontal position, and I thenunfasten the hook 9 and open the portion D ofthebox on its Verticalhinge c, and take the glass `plate Z on which. the picture isto'betaken, prepare it with collodion in the usual manner, and place itbetween the hooks k 7a and k' kv', and shut up the portion D of the boxagain and fasten the hook 9. I next unfasten the hook 10 and open theboxV D on the hinge d till the sensitizing-bath F and the plate pass ahorizontal position, when the plate'isat once covered with thesensitizing solution contained in the bath. A rocking motion onthe hinged is then given to D for a .sufficient time to subject the plate to theaction of the sensitizing solution, and D is then hooked up by the hooky to the Strap z, while the camera is adj usted to the proper focus, theglass Z remaining protected from the light by the screen H.

To adjust the camera, the hooks q q' are brought to the position shownin red Outline in Fig. 2 and the ground glass placed within or betweenthem, such glass now occupying the position that Will be occupied by theprepared plate l when D is shut up. When the camera has been adj usted,the ground glass is removed and the hooks q q' returned to the positionshown in black outline, which is near the sides of the box, and D isshut up. The screen H and the cap of the object-glass 'are then removedto allow the plate l to be acted upon by the light fora sufficie'nt'timeand the cap is put on.

lVhile the camera-box remains closed it is adjusted on the hinged boardsI J at a slight i nclination, to be indicated by thependulum 8 arrivingopposite to its index 8*, (see Fig.1,) and theplate Z istransferred'from the h'ooks k 7a k' k' to the developingbath by tnrniugthe shaft n, by means of its knob n, ina direction to raise the hooks kk, which 'lift the lower edge of the plate out of th'e'notchies in thehooks lc 7a, and the said hooks k k, having nonotches, in themselvesform inclined planes, down which the lower edge'ofthe glass is caused'toslide and over which .itis carried at first Vby the pressure of thehooks k' lo' and afterward by gravitation to the inclined plane t,downwhich the plate slides into the developing-bath G. The plate isshown in Fi'g. 2, in dotted red lines, at two stages of its progress tothe developing-bath. Thejapparatus then has given to it a rocking motionon the hinges w a: to make the developing vsolution run back and forthover the plate, and when this has been donesuficiently the door h isvopen'ed, the bath G drawn out, 'and the plate Z lifted out of the bathby the strip u, after which it is washed in the water bath, carriedwithin the box E, and then inserted in a grooved compartment of the saidbox.

What I claim as f my invention, and desire to secure by Letters Patent,'is-- 1. The arrangement of the sensitiziing and developing baths withinthe camera-'box and in relation'to the camera insuch man'ne'r'that I'cansensitize the plate, take the picture, and transfer the picture to thedeveloping-*bath without removing the plate from the dark room formed bythe camerajand bathsysubstantially as herein specified.

2. The combination of the hooks ik ak' k', and k k, the whole appliedand operating lsubstantially as and for the purpose herein 3. The hooksq q', applied and Operating substantially as and for the purposehereinset forth.
